Wind Speed in forecast ok, but reported Air Speeds in metrics are low

All wind speeds are modelled to 1 metres height from the ground. This modelling accounts for Wind Shear. This is the slowing of air low to the ground by obstacles and surface frictions.

A weather report usually is provided at wind speed at 10 metres above the ground and therefore is much higher.

For the purpose of modelling cycling dynamics the speeds we report are closer to that of real world wind speeds.
